Today we hiked the base of the Arenal Volcano. For $10, it was much more worth it than paying $50 to do the same thing with a tour group. We were able to go at our own pace, on our own time. The guy at the entrance told us it would take about 2 hours to hike 6.2k. I told P that we were going to do it in 1 hour and I started sprinting through the hike. P, of course, wanted to enjoy the scenery and all that nature stuff so he forced me to slow down :) We still made it in 1.5 hours.
